i was thinking of using a harken bullet cheek block code h092. Even if i noticed than some hc16 use an unknown cheek, must be hobie cat made.
The standard block is a Ronstan item but the Harken 092 works fine and is class legal.
You should be able to get either one at West or any decent rigger.
Like Dave says, you probably need to replace it every 20 or so years. At 25 it will be a goner!
